Embodiment Construction

[0016] The present invention will be further described now in conjunction with accompanying drawing. These drawings are simplified schematic diagrams only to illustrate the basic structure of the present invention in a schematic way, so they only show the components relevant to the present invention.

[0017] Such as figure 1 with figure 2 The shown precision shroud ring for an internal combustion engine includes a shroud ring body 1, and the inner wall of the shroud ring body 1 is composed of a stepped upper inner wall 2 and a lower inner wall 3; the upper surface of the shroud ring body 1 is provided with an upper V-shaped groove 4. The lower surface of the shield ring body 1 is provided with an annular lower V-shaped groove 5, and the outer wall of the shield ring body 1 is vertically provided with an annular groove 6; the diameter of the upper inner wall 2 is smaller than the diameter of the lower inner wall 3;

[0018] The upper V-shaped groove 4 includes two symmetric...

Abstract

The invention discloses a precision internal combustion engine shield ring. The precision internal combustion engine shield ring comprises a shield ring body; the inner wall of the shield ring body consists of an upper inner wall and a lower inner wall which are stepped; the upper surface of the shield ring body is provided with an upper V-shaped groove; the lower surface of the shield ring body is provided with an annular lower V-shaped groove; the outer wall of the shield ring body is provided with an annular groove vertical to a vehicle; the diameter of the upper inner wall is smaller than that of the lower inner wall. The precision internal combustion engine shield ring is simple in structure, reasonable in design, convenient to operate, relatively high in precision, tightly matched with parts of an internal combustion engine, good in dustproof effect, long in service life and free of frequent replacement, the production efficiency is improved and the cost is reduced.

Description

technical field [0001] The invention relates to the technical field of internal combustion engine accessories, in particular to a precision internal combustion engine shroud ring. Background technique [0002] An internal combustion engine is a kind of power machinery, which is a heat engine that directly converts the heat energy released by burning fuel inside the machine into power. Internal combustion engines in a broad sense include not only reciprocating piston internal combustion engines, rotary piston engines and free piston engines, but also rotary impeller gas turbines, jet engines, etc., but internal combustion engines generally refer to piston internal combustion engines. Piston type internal combustion engine is the most common with reciprocating piston type. The piston internal combustion engine mixes fuel and air and burns it in its cylinder, and the heat energy released makes the cylinder generate high-temperature and high-pressure gas. The expansion of the ...
